We're dividing 813744 by 81 
We want to figure out the number of times 813744 can be divided by 81.

Going ahead to step 1:
81 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 81

Let's proceed to step 2:
81 goes into 81 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 81 from 81.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 81

Advancing to step 3:
The number 81 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 81

Going ahead to step 4:
81 goes into 37 0 times with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtracting 0 from 37 leaves us with 37.
Take the next digit (4) from the dividend and append it to 37, then repeat: 374 / 81

Let's proceed to step 5:
When dividing 374 by 81, we get 4 with a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 1004.0
Subtract 324 from 374 to get 50.
Bring next digit (4) of the dividend behind the 50 and repeat the process: 504 / 81

Advancing to step 6:
504 divided by 81 is 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 10046.0
If we subtract 486 from 504, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
180 divided by 81 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 10046.2
Subtract 162 from 180 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
When dividing 180 by 81, we get 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 10046.22
If we take 162 away from 180, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 10046.22 with a remainder of 0.018.
